Product Details
NCD2100MTR - Non-Volatile Digitally Programmable Capacitor
NCD2100MTR from Littelfuse / IXYS Integrated Circuits Division is a single-output digitally programmable capacitor with non-volatile memory, supplied in a 6-pin 2 mm by 2 mm DFN on a 3,000-piece reel.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
NCD2100MTR sets capacitance between X1 and VSS from an 11-bit serial shift register or its stored non-volatile code. Its three internal capacitor banks provide 1024 selectable nominal values for trimming oscillators, RF stages and filters.
Key Advantages
A 6.6 pF to 37.553 pF nominal range offers fine electronic tuning with 0.063 pF minimum steps.
Non-volatile memory recalls the selected capacitance after power cycling.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
Feature Summary
Single-output non-volatile programmable capacitor
DA and CLK serial shift register; PV programming and verification
2.5 V to 5.5 V, -40 C to +85 C normal operation

Replacement Considerations
NCD2400MTR is a related product in the library. Confirm electrical behavior, package, pinout, ordering media and configuration before substitution.
Similarity of family name or package does not establish drop-in compatibility.
Manufacturer Information
Littelfuse publishes the IXYS Integrated Circuits Division NCD2100 controlled data sheet. NCD2400MTR is a related digital capacitor with a different control interface and range, so replacement requires circuit redesign.
Applications
Set a calibrated load capacitance in a VCXO or crystal oscillator circuit.
Tune capacitance-sensitive stages after board assembly.
Quality & Authenticity
Match the complete ordering code, package marking and reel or lot label to authorized-channel records. Inspect moisture handling and solderability requirements before assembly.
FAQ
What is the main function?
Single-output non-volatile programmable capacitor
What package is used?
6-WDFN Exposed Pad
Can the related part be substituted directly?
No. Validate all electrical, mechanical and configuration differences first.
Is the package image ready?
No. The registered package JPG is currently missing.
Engineering Notice
Use the latest manufacturer documentation for schematic, PCB, thermal and production approval. Distributor attributes are useful for sourcing but do not replace the official data sheet.
